Democracy is a conversation, and conversations rely on language. By hacking language, computers could make it extremely difficult for large numbers of humans to conduct a meaningful public conversation.
What it means to be fully human is to strive to live by ideas and ideals and not to measure your life by what you've attained in terms of your desires but those small moments of integrity, compassion, rationality, even self-sacrifice.
Not because you'll get it, but because you're doomed not to want it once you do. So the lesson of Lacan is, living by your wants will never make you happy.
So, desire supports crazy fantasies. This is what Pascal means when he says that we are only truly happy when daydreaming about future happiness. Or why we say the hunt is sweeter than the kill. Or be careful what you wish for.
Fantasies have to be unrealistic because the moment, the second that you get what you seek, you don't, you can't want it anymore. In order to
continue to exist, desire must have its objects perpetually absent. It's not the "it" that you want, it's the fantasy of "it."
Information is whatever connects different points into a network. Information doesn’t necessarily inform us about things. Rather, it puts things in formation.
Delusional or deceitful networks might occasionally arise in moments of historical crisis, in the long term they are bound to lose to more clear-sighted and honest rivals.
